  • Diogene : création de masques spécifiques de formulaires d’édition de contenus

    26 octobre 2010, par

    Diogene est un des plugins ? SPIP activé par défaut (extension) lors de l’initialisation de MediaSPIP.
    A quoi sert ce plugin

  • Failing to build ffmpeg for Android

    3 octobre 2018, par Hamed Momeni

    I’m trying build the ffmpeg sources for Android using two different approaches :

    1. https://yesimroy.gitbooks.io/android-note/content/compile_ffmpeg_for_android.html
    2. https://github.com/Khang-NT/ffmpeg-binary-android

    The problem here is that I am facing a somewhat similar problem in both the approaches so I guess the problem lies not with those scripts but there is some thing off in my environment. Here are the outputs of both build scripts :

    For approach #1 :

    /home/hamed/dev/android-tools/android-sdk-linux/ndk-bundle/toolchains/x86-4.9/prebuilt/linux-x86_64/bin/i686-linux-android-gcc is unable to create an executable file.
    C compiler test failed.

    If you think configure made a mistake, make sure you are using the latest
    version from Git.  If the latest version fails, report the problem to the
    ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    Include the log file "conflog.txt" produced by configure as this will help
    solve the problem.

    Android X86 builds finished

    And for approach #2 :

    checking how to print strings... printf
    checking for style of include used by make... GNU
    checking for arm-linux-androideabi-gcc... /home/hamed/dev/android-tools/android-ndk-r18/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc
    checking whether the C compiler works... no
    configure: error: in `/home/hamed/dev/projects/ffmpeg/ffmpeg-binary-android/build_scripts/opus-1.1.5':
    configure: error: C compiler cannot create executables

    I even tried redownloading the NDK fearing that the gcc compiler was corrupt but still the same error line appears.

    And this is the config.log file from the OPUS module of the second approach :

    This file contains any messages produced by compilers while
    running configure, to aid debugging if configure makes a mistake.

    It was created by opus configure 1.1.5, which was
    generated by GNU Autoconf 2.69.  Invocation command line was

     $ ./configure -v --prefix=/home/hamed/dev/projects/ffmpeg/ffmpeg-binary-android/build_scripts/build_dir --host=arm-linux-androideabi --enable-static --disable-shared --disable-doc --disable-extra-programs

  • FFmpeg hardware acceleration on Raspberry PI

    27 juin 2022, par Cristian Gabor

    I am building a program that use ffmpeg to stream webcam content over internet. I would like to know if it is possible to use the GPU for the streaming part on the raspberry pi model 3. If yes, how could I implement this on ffmpeg ?

    


  • Stream ffmpeg transcoding result to S3

    7 juin 2019, par mabead

    I want to transcode a large file using FFMPEG and store the result directly on AWS S3. This will be done inside of an AWS Lambda that has limited tmp space so I can’t store the transcoding result locally and then upload it to S3 in a second step. I won’t have enough tmp space. I therefore want to store the FFMPEG output directly on S3.

    I therefore created a S3 pre-signed url that allows ’PUT’ :

    var outputPath = s3Client.GetPreSignedURL(new Amazon.S3.Model.GetPreSignedUrlRequest
    {
       BucketName = "my-bucket",
       Expires = DateTime.UtcNow.AddMinutes(5),
       Key = "output.mp3",
       Verb = HttpVerb.PUT,
    });

    I then called ffmpeg with the resulting pre-signed url :

    ffmpeg -i C:\input.wav -y -vn -ar 44100 -ac 2 -ab 192k -f mp3 https://my-bucket.s3.amazonaws.com/output.mp3?AWSAccessKeyId=AKIAJDSGJWM63VQEXHIQ&Expires=1550427237&Signature=%2BE8Wc%2F%2FQYrvGxzc%2FgXnsvauKnac%3D

    FFMPEG returns an exit code of 1 with the following output :

    As you can see, I have a URL read error. This is a little surprising to me since I want to output to this url and not read it.

    Anybody know how I can store directly my FFMPEG output directly to S3 without having to store it locally first ?

    Edit 1
    I then tried to use the -method PUT parameter and use http instead of https to remove TLS from the equation. Here’s the output that I got when running ffmpeg with the -v trace option.
